As profiled in our last edition, a four-month trial of a soy biodiesel product in the mine fleet began on 1 June 2010. The product is being used to fuel the earthmoving fleet, in a bid to further reduce greenhouse emissions across the site. Alcoa will continue to monitor the project for the remaining weeks of the trial. A project evaluation will then occur to determine if Alcoa equipment to B20 soy-diesel. The second proposed alternative fuel trial aims to replace a small proportion of the current coal input with a carbon-based fuel known as HiCAL40. This alternative fuel is already successfully used in other industries and provides a range of benefits to the companies which use it. The success of these projects has PLANT OF THE ANGLESEA HEATH SILVER BANKSIA (Banksia marginata) Banksia…after Sir Joseph Banks marginata…from Latin, marginatus, bordered, referring to recurved leaf margins on some forms Size: Habitat: Foliage: Flowers: Did you know? 2m x 2m medium shrub coastal heaths, forest and woodland in NSW, Vic, SA and Tasmania linear leaves 15-60mm long and 313mm wide, often with recurved margins. Upper surface of the leaves is dull green, and the under surface is silvery, giving the plant its common name occur in cylindrical spikes which are 50-100mm long, 40-60 mm wide and pale yellow in colour Banksia marginata is one of the most difficult species to establish in the mine rehabilitation led Alcoa to believe there is scope for a trial at Anglesea Power Station to determine the potential to develop new markets for the product. Alcoa applied for an EPA Research, Development and Demonstration (RD&D) permit to conduct the trial, but the trial is not yet active and remains on hold while we continue to review a range of technical and environmental, health and safety (EHS) aspects of the project. No firm start date for the project has been decided at this point, but if and when it does get approval to commence we will keep our employees and the community updated through our existing communication channels such as this report, Talking Points, our bi-monthly Community Consultation Network meetings, our quarterly site newsletter and our website.

What environmental approvals are required for trials such at the HiCal40 Trial? We were advised by the EPA to submit a Research, Development and Demonstration (RD&D) application for the trial. This application requires approval from the EPA and has a 12 month timeframe. What sort of information was included in the RD&D Application? We engaged various consultants with knowledge on the HiCal40 product to make considerations on the potential impacts to air, water and land. The recommendations and information provided by the consultants was included in the application. What was your involvement in the HiCal40 Road show? I was part of the team who gave a presentation to all personnel on site. We wanted to ensure that everyone had a clear understanding of the trial intent, the testing that had been done and to give them an opportunity to ask questions face to face. We had lots of really good questions and discussions during the road show. If the trial does go ahead in the future, what will be required from EPA’s perspective? We will need to provide ongoing monitoring and reporting to the EPA throughout the trial duration and a comprehensive post-trial report.
